Another year, another NPC decision on Hong Kong. On Thursday, March 11, the National People’s Congress, with 2895 votes in favor and 1 abstention, approved the Decision on Improving the Electoral System of the Hong Kong Special Administrative Region (Decision) [关于完善香港特别行政区选举制度的决定], which takes immediate effect. The Decision comes on the heels of a series of events in the past two years: mass protests against the Hong Kong government’s extradition bill (since withdrawn), opposition lawmakers’ use of filibusters to delay proceedings, and pro-democracy primaries for the now-postponed 2020 Legislative Council election. (Almost fifty activists involved in the primaries have been charged with violating the Hong Kong National Security Law.) The Decision’s explanatory document cites all those events as evidence of the “clear loopholes and deficiencies” in Hong Kong’s current electoral system—which it says have been exploited by “anti-China, destabilizing elements” to attempt to seize the “power to administer [Hong Kong].” It is therefore “important,” the explanation continues, “to take necessary steps to improve the electoral system and remove existing institutional deficiencies and risks to ensure the administration of Hong Kong by Hong Kong people with patriots as the main body.” The Decision marks the first of those steps. Below, we will first provide an overview of the Decision, before discussing in detail the changes it will make to Hong Kong’s electoral system.
